Loft conversion skylights for Dinas Powys: the essentials
Loft conversion skylights in Dinas Powys means roof windows planned for loft rooms — light, headroom and escape. We cover the CF64 district and the rest of South Glamorgan, with a survey before any price is fixed.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Loft conversion skylights suit attic bedrooms, offices and en-suites.

Planning, building control and Dinas Powys
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
See our building regulations guide for U-values, glazing limits and self-certification.

Top-hung gives a clearer view and often suits escape use; centre-pivot is easier to clean and suits higher positions.

Correctly fitted insulation collars and linings keep the window surround warm and reduce condensation.
